Bat Inspection Survey
Inspection surveys are undertaken to record bat presence and evidence of use by bats both internally and externally within a built structure. They can be undertaken at any stage of the year, although any further emergence surveys that may be needed are seasonally restricted to the period May to September.
An inspection survey requires the surveyor to assess whether bats are currently present, have been present or have the potential to be present. A variety of equipment is used to examine the structure internally and externally this includes an endoscope, inspection mirrors, binoculars, and a high-powered torch. The following evidence would be recorded:
Some structures require the use of access platforms to fully inspect the external and internal walls and roof. All features of a structure are checked for bat activity and the presence of bats.
Inspection surveys of trees require either climbing or the use of access platforms depending on the location and state of the tree to be surveyed. The Wildlife Survey Unit employ LANTRA qualified tree-climbers, we also have extensive experience of the use of access platforms.
All survey methods follow the methodology given in the Bat Conservation Trust's Bat Survey: Good Practice Guidelines 2nd Edition.
